What management told investors in Q1
On 1 August 2026, the company reported Q1FY27 consolidated revenue of ₹302 Cr, down 3.4% YoY, while net profit rose 4.9% to ₹24.63 Cr as operating margin expanded by 126 bps to 13.7% (BSE filing, 1 Aug 2026). In a concall transcript filed on 6 August 2026, management attributed the revenue dip to disruptions caused by the West Bengal elections and retained the full‑year FY27 targets: 30% revenue growth and a ₹3,000 crore order‑inflow goal.
